Bede the Venerable
Catena Aurea · Markusevangelium 11
And they come again to Jerusalem: and as he was walking in the temple, there come to him the chief priests, and the scribes, and the elders, And say unto him, By what authority doest thou these things? and who gave thee this authority to do these things? And Jesus answered and said unto them, I will also ask of you one question, and answer me, and I will tell you by what authority I do these things. The baptism of John, was it from heaven, or of men? answer me. And they reasoned with themselves, saying, If we shall say, From heaven; he will say, Why then did ye not believe him? But if we shall say, Of men; they feared the people: for all men counted John, that he was a prophet indeed. And they answered and said unto Jesus, We cannot tell. And Jesus answering saith unto them, Neither do I tell you by what authority I do these things.
(ubi sup.) And indeed, when they say, By what authority doest thou these things, they doubt its being the power of God, and wish it to be understood that what He did was the devil’s work. When they add also, Who gave thee this authority, they evidently deny that He is the Son of God, since they believe that He works miracles, not by His own but by another’s power.
